seifieafionrorming parter Letters PatentNo. 47,746.| azuettMay 16, leca.i To a/ZZwhontf Lit-may concernr Be it known that I, NELsoN PALMER, of

` Hudson, in the county ofv ColumbiaA andiState thrashing-Inachinecrosswise of the thrashingcylinder, and Fig. 2 is a plan of said machinewi th the cover on top of the case removed.

Similar markspof reference denote the same parts.

The nature of my said invention consists in a ribbed or corrugatedcylinder receiving the grain, straw, or stalks lengthwise or nearlyparallel to the said ribs or corrugations, and thrashing out the grainor seeds against a ribbed or grooved rubber. The straw or stalks aredelivered upon an apron that acts to separate the grains or seeds,allowing them to fallaway while the straw is delivered in a conditionto. be bound into bundles, as the thrashin g operation does not inj urethe straw, but leaves the said straw nearly in the same condition asflail-thrashed straw.

In the drawings, a represents aframe of suitable size receiving thecorrugated or ribbed thrashing-cylinder b. This cylinder is to be` longenough to receive the straw or stalks widthwise, so that they shall passinto the' machine transversely or nearly parallel to the saidthrashing-cylinder. Below the said threshing-cylinder b, and partiallyat one side thereof, I make use of a concave rubber, c, that is attachedat its upper edge or corners by hinges or joints, so that it lmay bemoved nearer to or farther from the thrashing-cylinder b, according tothe character of grain or seeds to be thrashed. For adj ustin g thisrubber c, I employ levers d on fulcrums on the frame a, and l are pinsat the outer vends of the levers, entering holes in the frame, to retaiuthe parts when adjusted. This concave rubber may be adj usted by screwsor in any convenient manner. e is a board to direct the straw as itpasses in between the rubber c and thrasher b and prevent the grain,straw, or stalks falling down on the opposite side of the thrasher b.

The grain or st'alks4 are=tofbe fcd intofthe`` thrashing-machine in anyconvenient manner. I however prefcr and use a table, j`,to'` re' ceivethe bundzle of lgrain'oriother material to be thrashed, and upon whichit is separated and loosened.

g is a slotted grate extending from the table f toi the upper edge ofthe rubber a, and

curved, as shown. Beneath this grate is the i feeding-cylinder h, thatis on an axis parallel or nearly so to the aXis of the thrasher b, andis provided with ranges of teeth or spikes that as the cylinder hrevolves come above the surface of the grate g suffioiently to take thegrain or other material and carry it transversely to thethrashing-cylinder. The shape of the grate g is such that the ends ofthe spikes or teeth of the cylinder li pass below the surface of` saidgrate adjacent to' the rubber c. Supports z' and end pieces, lc, may

be provided to the table f to facilitate the handling of the grain. Overthe thrasher is a cover, l, to inclose the parts, and an endless apron,m, is provided to convey` away the straw or stalks.

`a is a division or wind board, between which and the cover l is a monththrough which the dust is allowed to escape, and the grain 'and straware thrown out below the wind-board n upon the endless apron m. Theapron lm is sustained by the rollers o o, one of which is propelled by abelt from the thrashing-machine, and the apron itself is formed bytransverse slats attached to endless belts in the usual manner. Beneaththe said apron, at the lower end thereof, is a table, p, and this servesto arrest the momentum of grain and straw or stalks as thrown out fromthe thrasher, and an apron may hang down from 'the lower edge of theboard a to check the momentum of said straw and grain as they issue fromthe thrasher to the apron. At the -upper end of the table p slats q arelfitted that extend upward and parallel with the edges of the belt tosustain the straw while carried up by the apron m, and at the same timeallow thegrain to fall away beneath the apron, while the straw itself iscarried to the upper end of the apron and delivered in a form adapted tobeing bound into bundles.

The apron m may be fitted on a frame, r, so that it can be detached, ifdesired, from the frame ofthe thrashing-machine. I have represented suchapron-,frame r as entered be-. t'veen the main frame a-and held up bybutt ms 8, turned up beneath the side pieces of s 1ch frame r. A

The apron may be shaken to shake out the grains or seeds, for whichpurpose the slats of said apron may be drawn over stationary inclines ortriangular blocks on the frame r at the ends of said siats.

The belts for driving the cylindcrs b and h and the apron m may bearranged in any desired manner, and the thrashing-cylinder and concavemay be of Wood or metal, or may be of Wood covered by sheetmetal or ofslats secured upon heads or a cylinder.

What I elaim, and desire to secure by Letters Patent, is-

1. The method hcrcin specifiod of thrashin g grain transversely by thecombined action of the fee'ding device, the corrugated cylinder, and thecurved rubber, as set forth.

2. A revolving cylinder armed With teeth or spikes, in combination vwiththe guard g for feeding in the straw or stalks transversely to thethrashing mechanism, substantiaily as specified.

3. The guard g, in combination With the feeding-cylinder h,thrashing-cylnder b, and concave rubber c, substantiaily as specified.

In witness whereof Ihave hereunto set my signature this 27th day ofJanuary, 1865.

N. PALMER.
